Topspeed Header Install Completed!!!!!
FINALLY done....and it only took 8 hours to do. 
If I had to do it again...i think I'd pay someone to get it done. Overall the headers sound great! It gave my exhaust a little more throatier sound. Iono about the gains but my friend said that he felt that my mid and high gained something. I dont really trust my butt dyno....but thats what he said. These things are never coming off my car....it's just too much of a PITA to do headers.

you should be proud of the 8 hours dude... i had mine done by shop who are experts on the VQ35 and it took them 7 hours to do mine on a lift
do you hear any rasp? b/c i get some but i dunno if it's from the headers, cats, y-pipe, or the combination of all of them

wow, the shop i used has it down pat, 4hours! they installed enough of them(crawfords, topspeeds, dc...etc) to do it that quick.....and get this, on jackstands!
yep, feel it pulls from mid to high pretty good.....no rasps i could hear....if anything i hear more air swhoosing through the manifolds......

i can't really tell if i have rasp... sometimes, when i get on the throttle, i hear what sounds like a "rattle"... it only happens for a second or two and then is gone, but it bothers me. most of the time it only happens at WOT, but sometimes, if the engine isn't warmed up yet, it'll happen at partial throttle too
it feels like it's coming from my y-pipe (Fujitsubo) although i can't be certain if it's from that or from the combo of the headers (TopSpeed) cats (Crawford) and y-pipe all together.
it was especially noticeable to me when my car was on the dyno and i was standing behind it. i'm gonna put the car on a lift and see if any of the exhaust components are making contact with the frame or something, perhaps from the engine's torque movement... but i doubt it. to me, it sounds more like it's coming from inside the exhaust pipes themselves. any thoughts?

Yeah I hear a rattle too. Not too sure where it's coming from either. I was kinda hoping that getting a new set of cats would help solve that problem but since you have cats and it's doing the same maybe it's not that. All in all i dont really hear the rattle sound unless i have my music down...most of the time my music will block that rattle sound. =)

i had to get another set of headers from top speed. the one on the right (as you look at the car from the front) has a leak inside where the pipes go into the collector. getting the new one put on monday.

how'd you detected that leak? was it something that was apparent by looking at it, or was there exhaust smell that you noticed? topspeed gonna replace the headers right?, because i remember something about their lifetime warranty thing when i was reading up on them.....

it was very audible. it first sounded like an exhaust leak, like somebody didn't seal the gasket right or torque down all of the bolts. so i took it back in. they (the garage)put it on a lift, we looked at it, sure enough, a leak coming from inside the collector, before the flange. called top speed, i had to buy one, get it replaced, and then they said they would honor a refund of the second purchase... nevermind the $100+ it's going to cost for me to get the faulty one replaced. oh well. hope it works. it'll be here friday.

For the longest time I thought it was my kinetix cats--I've bent heat shields, had custom hangers installed etc...only to discover that it was my stock muffler all along...go figure...baffles broke down inside (this happened approx 5,000 miles after my cat install-not sure why) Try pressing on the metal to feel for flexing--or pulling or pushing on the muffler while a buddy hits the gas......
The "rattle" seems to be amplified when cold..not as bad when the motor is warm but still noticeable at certain loads and various rpms....I'm very frustrated with this "rattle"...I tried a few things to repair the stock muffler..I.e. stretched the metal with a hammer at the seem which helped for a day or two but the internals continued to deteriorate....Long story short...I cant wait 4-14 weeks for a Legalis R (my first choice)...So I will be selling my y-pipe and ordered a new cat back system....I went with the Borla--In stock! 1,000,000,000 warranty and I really like the sound with high flow cats.....
xstarpro, please keep me updated on this... i never would have thought that it was the stock muffler (perhaps it breaks down b/c of the added flow from the rest of the mods?)
if it is in fact the muffler, i'll be one happy camper if, when i replace that **** with something aftermarket and the rattle disappears
